A disadvantage of this device is that printing forms by means of their codes are only assigned to a specific printing unit, but not to their installation location on the cylinder, so that their assembly on the cylinder is in no way ensured in the case of several printing plates to be arranged on the cylinder according to an allocation plan provided for this cylinder.

By the US 2002/0050216 A1 a device for assigning to be mounted on cylinders of a printing machine lifts is known, wherein in a manual installation of the lifts by operators, the location-correct assignment of the lifts to the cylinders by reading carried on the lifts features. With this procedure, mistakes can be made. B. not be excluded by confusion. A message indicating a possible incorrect assembly is not issued.

By the DE 39 40 795 A1 For example, a method and apparatus for automatically feeding a printing plate to a plate cylinder or for discharging a plate cylinder of a rotary printing machine are known. The method for automatically feeding a printing plate to a plate cylinder of a rotary printing press, the plate cylinder including means for clamping and clamping the printing plate, provides that the printing plate is placed in a storage chamber of a Druckplattenzuführ- orabführvorrichtung, the Plate cylinder rotated in a Druckplattenzuführstellung and the pressure plate is fed by means of a number of transport rollers of a clamping device of the plate cylinder. The method of automatically discharging a printing plate from a plate cylinder of a rotary printing press, the plate cylinder including means for releasing and releasing the printing plate is characterized in that the plate cylinder rotates forward to a printing plate release position that a clamping flap for detecting a printing plate end is opened the plate cylinder is rotated backwards so that a clamping flap for detecting a printing plate beginning opened and that the printing plate is fed by means of a number of transport rollers of a storage chamber of Druckplattenzuführ- or -abführvorrichtung. The device for carrying out the aforementioned method has at least one transport roller designed as a drive roller and a transport roller designed as a pressure roller, wherein the pressure roller can be adjusted to the drive roller. In addition, various adjusting means, a pivotally mounted pressure roller for pressing the pressure plate to the plate cylinder and ejection fingers may be provided, wherein the ejection fingers may have tips which are pivotally mounted in the periphery of the plate cylinder. Also, the storage chamber of Druckplattenzuführ- or - be discharged pivoting about a hinge.

The DE 39 40 796 A1 describes a device for automatically changing a printing plate on a plate cylinder of a rotary printing press, the plate cylinder including means for clamping and clamping the printing plate, the printing plate changing device having two storage chambers, so that a plate cylinder dissolved pressure plate can be guided by means of transport rollers in the one storage chamber, while a printing plate stored in the other storage chamber is fed by means of transport rollers to a clamping device of the plate cylinder.

By the EP 0 214 549 B1 is a device for automatically feeding a Printing plate to form a cylinder of a printing press or for discharging a printing plate of a form cylinder known, wherein the printing plate to be supplied to the forme cylinder is guided by lateral positioning elements in a desired position, the blanking cylinder, the supply of the printing plate takes place from a substantially horizontal storage position.

By the DE 103 14 341 B3 a method for operating a system at least for supplying at least one stored in a printing forme magazine printing form to a cylinder is known, wherein a code reader detects a coding of the printing form, wherein errors such as a double assignment or a misregistration of a pressure point on the cylinder by a system preferably to a Control station of the printing press remote message can be detected.

The invention has for its object to provide a system for checking the assembly of a printing forme magazine, which is inexpensive to implement and by which the process reliability is increased during operation of the printing press.

The object is achieved by the features of claim 1.

The achievable with the present invention consist in particular that the process reliability is increased in an operation of the printing press, because a permutation of stored in a printing forme forms printing forms is recognized before their respective placement on a forme cylinder of a printing press and the error can be corrected. As a result, a faulty pressure is avoided. Because spoiled copies of the printed product are avoided as a result of reversed printing forms, consumables such as the substrate, z. As paper, and Color is not wasted, which saves costs. Since printing forme magazines can perform a change of printing plates on a forme cylinder of a printing machine in a very short, manually unattainable time, this time advantage in the set-up of the press can fully come into their own, since it is not nullified by a correction in the disk allocation. An automatic printing forme magazine requires only about 10% to a maximum of 20% of the time required for a manual execution of changing this for a change of printing plates on a forme cylinder Printing forms would be required. If a mishandling of a printing forme magazine is detected before the start of a new, planned production, sufficient time will usually be left in a printing company to remedy this error. There is no delay in the production process.

Another advantage of the solution found is that only a small number of code readers are needed, whereby the cost of the system for checking the assembly of a printing forme magazine can be kept within reasonable limits. Thus, not every printing form is associated with a single code reader, but the coding of a plurality of printing forms stored in the printing plate can be detected simultaneously or successively together with the same code reader, which significantly contributes to a cost-effective implementation of the system for checking the assembly of a printing forme magazine, since each code reader in the overall system accounts for a significant share of the costs. This advantage is made possible in that a detection area of the code reader is divided into a plurality of individually activatable viewing zones, wherein each of the viewing zones is selectively readable.

It is also advantageous that a printing form is traceable in its respective use due to detection of its individual coding. This registration option is very helpful for statistical evaluations.

Embodiments of the invention are illustrated in the drawings and will be described in more detail below with further advantages.

The surface has a support side, which is referred to below support surface 02, with which the elevator 01 rests in the arranged on a lateral surface 07 of a cylinder 06 state ( Fig. 2 ). The back of the support surface 02 is a work surface which, in the case where the elevator 01 is formed as a printing forme 01, is provided with a printed image or at least can be provided with a printed image. The elevator 01 has two opposite ends 03; 04 preferably each with angled Einhänbringeln 13; 14, wherein the ends 03; 04 limit the bearing surface 02 and wherein the suspension legs 13; 14 each preferably extend entirely or at least partially across the width B of the elevator 01. The bearing surface 02 of the elevator 01 is flexible at least along the length L and in an arrangement of the elevator 01 on the lateral surface 07 of the cylinder 06 whose curvature can be adapted ( Fig. 2 ). When the printing forme 01 is arranged on the lateral surface 07, the length L of the bearing surface 02 thus extends in the direction of the circumference of the cylinder 06, whereas the width B of the bearing surface 02 extends in the axial direction of the cylinder 06.

At least at one end 03; 04 of the elevator 01 ( Fig. 1 ), but preferably at both ends 03; 04 are along a bending edge 11; 12 each a folded suspension leg 13; 14 formed, wherein the suspension legs 13, 14 in a narrow, in particular slot-shaped opening 09 of the channel 08 of the cylinder 06 (FIG. Fig. 2 ) insertable and there by means of a holding device, for. B. a clamping device can be fastened. For example, based on the length L of the non-curved, flat bearing surface 02 of the uninstalled elevator 01 at the end 03 a suspension leg 13 at the bending edge 11 by an opening angle α1 or at the end 04 a suspension leg 14 at the bending edge 12 by an opening angle β1 folded ( Fig. 1 ), wherein the opening angle α1; β1 usually lie between 30 ° and 140 °. If the opening angle α1 is assigned to the leading end 03 of the elevator 01, it is preferably executed at an acute angle, in particular it is 45 °. The opening angle β1 at the trailing end 04 of the elevator 01 is often preferably greater than 80 ° or obtuse-angled, in particular it is 85 ° or 135 °. The bent suspension leg 13 at the leading end 03 has a length I13, which z. B. in the range of 4 mm to 30 mm, in particular between 4 mm and 15 mm. The bent suspension leg 14 at the trailing end 04 has a length 114, the z. B. 4 mm to 30 mm, in particular between 8 mm and 12 mm, with the shorter length measure is preferred to simplify removal of the suspension legs 13 as possible; 14 to ensure from the opening 09 of the channel 08.

The Fig. 2 shows in a simplified sectional view of a cylinder 06 with a lateral surface 07 and a channel 08, which has a narrow, slot-shaped opening 09 with a slot width S to the lateral surface 07, wherein the slot width S is less than 5 mm and preferably in the range of 1 mm 3 mm. The opening 09 has in the production direction P of the cylinder 06 has a front edge 16 and a rear edge 17 on. Between the extending from the front edge 16 to the channel 08 toward wall 18 and an imaginary, resting on the lateral surface 07 of the cylinder 06 on the opening 09 tangent T09 an acute opening angle α2 is formed, which is between 30 ° and 50 °, preferably 45 ° is. The bent suspension leg 13 at the leading end 03 of the elevator 01 is thus preferably positively connected to this front edge 16 of the opening 09, because the opening angle α1 at the leading end 03 of the elevator 01 is preferably adapted to the opening angle α2. The same applies at the trailing end 04 of the elevator 01. Between the wall 19 extending from the rear edge 17 to the channel 08 and an imaginary tangent T09 lying on the lateral surface 07 'of the cylinder 06 is a tangent T09 Aperture angle β2 formed, which is either between 80 ° and 95 °, preferably 90 °, or between 120 ° and 150 °, preferably 135 °. The bent suspension leg 14 at the trailing end 04 of the elevator 01 is thus preferably positively clamped at this rear edge 17 of the opening 09, because the opening angle β1 at the trailing end 04 of the elevator 01 is at least approximately adapted to the opening angle β2.

In the channel 08 are z. B. at least one preferably pivotally mounted holding means 21 and a preferably biased spring element 22 is arranged, wherein the spring element 22, the holding means 21 z. B. against the folded suspension leg 14 at the trailing end 04 presses, which is hooked to the opening 09 at its rear edge 17, whereby the suspension leg 14 at the trailing end 04 at the extending from the rear edge 17 to the channel 08 extending wall 19 becomes. To release the pressure exerted by the holding means 21 pressing in the channel 08, a setting means 23, preferably a pneumatically actuable adjusting means 23 is provided, which pivots the holding means 21 against the force of the spring element 22 during its actuation. The holding device described by way of example consists essentially of the holding means 21, the spring element 22 and the adjusting means 23.

The exemplified cylinder 06 is preferably such that on its lateral surface 07 a plurality of, preferably similar elevators 01 can be arranged. If the cylinder 06 is designed as a forme cylinder, it can in its axial direction side by side z. B. with up to six plate-shaped printing plates 01 are occupied. It is also preferably provided that more than one elevator 01 can be arranged on the cylinder 06 in the direction of its circumference. Thus, in the cylinder 06 under the lateral surface 07 z. B. two axially extending to the cylinder 06 channels 08 may be provided, which have for attachment of elevators 01 axially to the cylinder 06 extending openings 09, wherein the openings 09 at the periphery of the cylinder 06 z. B. offset by 180 ° to each other, if two elevators 01 are to be arranged on the cylinder 06 along its circumference one behind the other. In this assignment of the cylinder 06 with two along its circumference successively arranged elevators 01, the leading end 03 of the one elevator 01 is fixed in the one channel 08, whereas the trailing end 04 of the same elevator 01 is fixed in the other channel 08. For the or the other arranged on this cylinder 06 lifts 01 applies accordingly. If several elevators 01 are arranged next to one another in the axial direction of the cylinder 06, they can advantageously also be arranged offset to one another. The offset can z. B. individual lifts 01 or groups of elevators 01 relate, each z. B. offset by half a length L of the elevator 01 to each other, which, however, requires that more channels 08 with associated openings 09 or at least with portions thereof are introduced into the cylinder 06 along the circumference of the cylinder 06 to the aforementioned channels 08 and openings 09 z.

B. two printing plates 01 having printing machine, ie a so-called 6/2 machine, z. B. used in newspaper printing.

In the following, a method for mounting a flexible elevator 01 on a cylinder 06 of a printing machine is described by way of example, wherein two elevators 01 can be arranged on the cylinder 06 along its circumference one behind the other and wherein each elevator 01 has a leading end relative to the production direction P of the cylinder 06 03 and a trailing end 04 ( Fig. 3 ). At the leading end 03 of the elevator 01 a suspension leg 13 is formed, said suspension leg 13 is bent to the extended length L of the elevator 01 with an opening angle α1 of a maximum of 90 °, preferably 45 °. In the cylinder 06 at least one preferably slot-shaped opening 09 are provided with a first edge 16 in the production direction P of the cylinder 06 and a second edge 17, wherein the edges 16; 17 in the axial direction of the cylinder 06 preferably parallel to each other. The leading end 03 of the elevator 01 is z. B. by means of an acting on the trailing end 04 of the elevator 01 thrust cylinder 06 preferably tangentially fed in its production direction P until the suspension leg 13 is present at the leading end 03 behind the second edge 17 of the opening 09 to the cylinder 06, so that the leading End 03 trained suspension legs 13 engages in a rotation of the cylinder 06 in the production direction P as a result of acting at least on the leading end 03, directed to the cylinder 06 radial force FR in the opening 09 and hooked to the first edge 16. In the event that the elevator 01 with its formed at the leading end 03 suspension leg 13 on the lateral surface 07 of the cylinder 06 is supported supporting it, the radial force FR z.

The thus performed bending of the leading end 03 of the elevator 01 should, however, only be so strong that the suspension leg 13 attached there still rests securely against the lateral surface 07 of the cylinder 06. To support the safe concern of Einhänlegeels 13 on the lateral surface 07 of the cylinder 06 can, for. B. the support member 24 are employed on the elevator 01, whereby the elevator 01 is held with its leading end 03 close to the lateral surface 07 of the cylinder 06.

B. counter to the direction of production P of the cylinder 06, hooked hooks hooked hook 13 at the leading end 03 of the elevator 01 at the first edge 16 of the opening 09 a. A rolling element 24 placed against the cylinder 06 can assist the mounting of the elevator 01 on the cylinder 06 by the rolling element 24 rolling up the elevator 01 onto the cylinder 06. At the trailing end 04 of the elevator 01 of the suspension leg 14 is formed, said suspension leg 14 is pressed by the rolling element 24 in the course of rolling up the elevator 01 on the cylinder 06 into the opening 09 of the cylinder 06.

It is advantageous to arrange an articulated, preferably pivotable baffle 49 in front of the opening of the printing forme magazine 39 which can be directed onto the forme cylinder 33, close to the forme cylinder 33 ( Fig. 5 ), with which a released from an opening 09 in the forme cylinder 33 trailing end 04 of a printing plate 37 targeted to the shaft 42 for Recording the abzunehmenden printing form 37 is passed. In particular, an erroneous access to the shaft 44 is obstructed with the guide plate 49 for a printing plate 37 to be removed from the forme cylinder 33, in which at least one new printing plate 37 is provided or at least ready for delivery. Likewise, at the arranged below the paper web 46, cooperating with the forme cylinder 31 printing forme magazine 38, the attachment of a guide plate 49 may be advantageous, but for the sake of clarity in the Fig. 5 not shown.

Another embodiment of a printing press with printing forme magazines results in conjunction with a printing machine, for. As a working in a wet offset printing process or in a dry offset printing multicolor offset printing machine whose printing works preferably in bridge design or a compact design, ie a low in construction height printing machine with eight pressure points, as exemplified by the Fig. 36 shows, in at least one frame 97 on a foundation 96 are arranged one above the other. A printing material 46, preferably a paper web 46, is in this case fed to the printing press and passed vertically through the printing units. In the Fig. 36 are exemplified four in the transport direction of the paper web 46 successive printing units, the right and left of the paper web 46 each have a transfer cylinder 32; 34 with a form cylinder 31; 33, wherein in a printing unit on the paper web 46 opposite transfer cylinder 32; 34 roll on each other. The paper web 46 is z. B. introduced by means of a first printing unit arranged first paper guide roller 92 to the first printing unit and derived by means of a fourth printing unit arranged second paper guide roller 93 from the fourth printing unit. Each form cylinder 31; 33 is associated with at least one inking 94, the details of which will not be discussed here. Each form cylinder 31; 33 is a printing form magazine 38; 39, each preferably two shafts 41; 42; 43; 44 has. As in the previous in connection with the Fig. 5 described embodiment is also here each printing forme magazine 38; 39, at least its storage position for a printing form 36 to be stored; 37, in the working position preferably substantially horizontally or only with a slight inclination of less than 15 ° to the forme cylinder 31; 33 aligned. In the working position of the printing form magazine 38; 39 is at least one printing plate 36; 37 between the shafts 41; 42; 43; 44 and the forme cylinder 31; 33 interchangeable, either by a no longer required to execute a print job 36; 37 from the forme cylinder 31; 33 removed and into the shaft 41; Introduced 42 or a new to execute the print job printing plate 36; 37 from the shaft 43; 44 brought out and on the forme cylinder 31; 33 is mounted. The structural features of the printing form magazines 38; 39 may in this embodiment those of the previously in connection with the Fig. 5 correspond to described embodiment. It is advantageous if the implementation, in particular the completion of a printing form change is monitored by sensors. Likewise, the printing form magazines 38; 39 in conjunction with the form of cylinders 31; 33 controllable such that preferably from a printing press associated control station from selectively a printing plate change can be initiated. Because the printing form magazines 38; 39 during an ongoing production of the printing press can be prepared for a printing plate change, the standstill of the printing units requiring setup time is reduced to an extremely short period of z. B. less than two minutes, preferably less than ninety seconds, for a complete change of all printing plates 36; 37 arranged in this printing press units. Depending on the design of the printing units z. B. ninety-six printing plates 36; 37 at the same time in use. Such a rapid printing plate change even with a larger number of printing plates 36; 37 greatly increases the economics of the press because of its extremely short downtime.

Further details regarding a method and a device for carrying out the method will now be described by way of example with reference to FIG FIGS. 6 to 35 explained. It shows Fig. 6 a form cylinder 33 with two circumferentially offset by 180 ° channels 08 and two pressure molds 37 arranged one behind the other along the circumference, wherein the suspension leg 14 folded at right angles to the end 04 of each printing forme 37 is held by a holding means 21 pressurized by a spring element 22 on a wall 19 on the wall 19 in the direction of production P of the forme cylinder 33, wherein the wall 19 extends from a rear edge 17 of the channel 08 opening opening 09 to the channel 08, wherein the holding means 21 can be solved by the operation of a spring element 22 counteracting pneumatic actuator 23. At the extending from the front edge 16 of the same opening 09 to the channel 08 toward wall 18 of the acute-angled bent suspension arm 13 is applied form-fitting manner at the leading end 03 of the other along the circumference of the forme cylinder 33 arranged printing form 37. For details on the mounting of the printing plates is on the Fig. 2 directed.

Fig. 6 also shows an engageable by pneumatic actuation of the forme cylinder 33 pressure element 24 in the form of a pressure roller 24 or pressure roller 24. Similarly, close to the forme cylinder 33 is a parallel to the axial direction pivotally mounted alignment device 51 with two diametrically arranged laterally on a printing plate 37, wing-shaped stops 52; 53 provided, wherein the alignment device 51 each with one of their stops 52; 53, a printing plate 37 to be mounted temporarily fixed during its feeding to the forme cylinder 33. The stops 52; 53 z. B. each formed as a lateral guide plate, wherein the stops 52; 53 z. B. on a pivotable traverse, z. B. a square tube are arranged. The stops 52; 53 differ z. B. in their position based on the axial direction of the forme cylinder 33, so that z. B. for a printing plate 37 simple width of the stop 52 and for a printing plate 37 in the panoramic size of the stopper 53 is brought by a corresponding pivoting of the alignment device 51 is used. The stops 52; 53 may be axially adjustable to the forme cylinder 33 for the required width of the printing plate 37.

Of the Fig. 6 are also more details of the printing plate magazine 39 can be removed. That in the FIGS. 6 to 35 embodiment shown is based on a variant of the printing forme magazine 39, in which an upper shaft 44 for providing a to be mounted on the forme cylinder 33 printing plate 37 as an independent unit independently of a lower slot 42 for receiving a form cylinder 33 removed print form 37 is operable. Both shafts 42; 44 can be used as individually and independently usable and thus independently functional units. This application is of interest if z. B. only the feed of the forme cylinder 33 is to be automated with new printing plates 37, whereas the decrease of used printing plates 37 is performed by an operator. If both shafts 42; 44 are formed in the printing forme magazine 39, results in a fully automatic printing form changer. Both shafts 42; 44 each have all necessary for storing and conveying of printing plates 37 devices and are preferably constructed very compact. In particular, they have despite their capacity of at least two printing plates 37 a low overall height. The height is z. B. less than 150 mm, preferably less than 100 mm.

In the in the FIGS. 6 to 35 Shown embodiment, the shaft 44 is arranged horizontally and aligned tangentially to. As a result, the force FG exerted on the printing form 37 is used in the best possible way to support functions described below. In the shaft 44 is a support 54, on which a to be mounted on the forme cylinder 33 first printing plate 37 with its folded Einhänbringeln 13; 14 can be set up or stored. A stored on the pad 54 printing form 37 is located there z. B. with their entire extended length L on. The pad 54 is preferably not the entire surface, but in the form of parallel strips 54 or slides 54 formed. The suspension leg 14 at the trailing end 04 of the first printing plate 37 is located in the shaft 44 on the side facing away from the forme cylinder 33 on a preferably vertical stop 56, wherein the stop 56 of a conveyor 57 linear and parallel to the support 54 in the direction of the opening o39 of the printing plate magazine 39 is movable to promote this first printing plate 37 by a translational movement and preferably free from deformation at least as long as the shaft 44 until the suspension leg 13 at the leading end 03 of this first printing plate 37 can engage in the slot-shaped opening 09 of the forme cylinder 33 , The stopper 56 thus serves in the slot 44 for the first printing plate 37 as an abutment position and at the same time has the function of a slider 56. If this first printing plate 37 has at the trailing leg 14 at its trailing end 04 at least one register punching, the stop 56 z. B. advantageously also as a perpendicular to the support 54 standing, connected to the conveyor 57 register pin 56 may be formed so that with the application of the first printing plate 37 on the stop 56 for them a Vorregisterung takes place with respect to their side register. The conveyor 57 is z. B. as a belt drive 57 or as a linear drive 57, preferably as a pneumatic linear actuator 57, in particular as a rodless, double-acting linear actuator 57 is formed.

In the shaft 44 there is a holder 58, in particular printing form holder 58 for holding at least one second printing forme 37 to be mounted on the forme cylinder 33 Fig. 13 shown, the second printing plate 37 from the printing form holder 58 above the support 54, ie at a distance a54 above the support 54 z. B. thereby, that the printing form holder 58, for example, on the side facing away from the forme cylinder 33 has a movable parallel to the support 54 piston 59 or slider 59, at the end of a holding element 61, z. B. L-shaped angle 61, is arranged, wherein the second printing plate 37 above the support 54 between the angle 61 of the extended slider 59 and in the region of the opening o39 of the printing forme magazine 39 arranged further holding element 62, z. B. a rigidly arranged stop 62 is clamped. The distance a54 in this case has a value which is preferably between twice and four times the length I14 of Einhänlegeels 14 at the trailing end 04 of the second printing plate 37. The clamping of the second printing form 37 takes place in that a clear distance a58 between the angle 61 of the extended slider 59 and the stop 62 is set shorter than the extended length L of the second printing plate 37. The stop 62 in the region of the opening o39 of the printing forme magazine 39 preferably has a chamfer 63, at which the suspension leg 13 on can support the leading end 03 of the second printing plate 37, wherein the bevel 63 of the stopper 62 and the L-shaped angle 61 on which the suspension leg 14 is supported at the trailing end 04 of the second printing plate 37, facing each other. Since the second printing plate 37 is flexible, in particular along its length L, it bulges in its clamped state between the angle 61 and the stop 62. The slider 59 of the printing plate holder 58 is preferably linearly movable parallel to the support 54 and preferably has two stable operating positions, namely a stable operating position in the retracted, the second printing plate 37 releasing state and in the extended, ie the second printing plate 37 clamping state. In a variant of the printing form holder 58, the arrangement of the movable slide 59 and rigid stopper 62 are interchanged, so that the slider 59 is in the region of the opening o39 of the printing forme magazine 39 and the stop 62 on the side remote from the forme cylinder 33 side. As an alternative to the described linear mobility, the angle 61 or the stop 62 can also be arranged to be pivotable about a pivot axis aligned parallel to the width B of the printing forme 37. A clamped between the angle 61 and the stop 62 printing plate 37 is located at its upper or first storage position, while a stored on the pad 54 printing plate 37 assumes a lower, second storage position in this state, the printing plate 37 in the second storage position before her Transport to the forme cylinder 33 is cached. By an operation, preferably by a remote from, z. B. made by a belonging to the press control panel changes the printing plate 37 within the shaft 44 from its upper, first storage position to its lower, second storage position. Printing forms 37 stored in the first storage position and in the second storage position are spaced apart, e.g. B. along its length L with the distance a54, so they do not touch and consequently can not damage.

Another embodiment of the printing plate holder 58, which advantageously allows a particularly low overall height for the shaft 44, provides the second printing forme 37 above the support 54 extending in a single plane in the axial direction of the forme cylinder 33 with at least one retaining element 64 in an upper storage position to hold, with the retaining element 64 z. B. as a guide rail 64, preferably as two mutually parallel guide rails 64, is formed ( Fig. 7 to 9 ), wherein the guide rails 64 hold the second located in the slot 44 printing plate 37 at its two longitudinal sides along at least part of its length L in the upper storage position. The design of the printing form holder 58 with guide rails 64 assumes that the suspension legs 13; 14 at the ends 03; 04 of the second printing form 37 do not extend over the full width B of the printing plate 37 by not reaching the longitudinal sides of the printing plate 37. The longitudinal sides of the printing plate 37 thus form in the area of the support surface 02 of the printing plate 37 a projection with respect to the Einhänbringeln 13; 14. This projection is necessary to make the printing plate 37 in the guide rails 64 feasible. The holding element 64, in particular each guide rail 64, z. B. from a U-shaped, each one of the longitudinal sides of the printing plate 37 with a certain play encompassing strap into which the second printing forme 37 is inserted from the side facing away from the forme cylinder 33 side. The second printing form 37 is thus held by the guide rails 64, preferably in a narrow region of its side, wherein the holder acts in particular as a vertical support and thus as a support against the force acting on the printing plate 37 gravity FG. The guide rails 64 are preferably made of a dimensionally stable material such as metal or plastic.

In order to deposit a second printing form 37 held by the guide rails 64 on the support 54, at least one of the guide rails 64 is in the direction of the width B of the second printing form 37 movable. Preferably, however, both guide rails 64 along the width B of the second printing plate 37 are movable in opposite directions, so they at least briefly remove each other and their distance from each other such that they no longer support the longitudinal sides of the printing plate 37 vertically, whereby the second printing plate 37 due to at its attacking gravity FG between the guide rails 64 passes through the support 54. If the holding element 64 in a first operating state, the second printing forme 37 z. B. holds by an electric or magnetic force in the upper storage position, the holding member 64 preferably changes remotely from its first operating state to a second operating state, wherein the second operating state causes the holding member 64 that the printing plate 37 and the holding member 64 from each other and the printing forme 37 upon release from the retaining element 64 in the shaft 44 by a free fall and thus alone by the force acting on her gravity FG in the preferably immediately vertically below the upper storage position lying storage position changes. The second printing plate 37 is held in the lower and also in the upper storage position in the shaft 44 at an inclination of less than 15 °, preferably horizontally. At least the guide rails 64 designed as a support bearing for the second printing forme 37 have in their longitudinal extension only this slight inclination or a horizontal course.

A release of the second printing forme 37 from the laterally engaging guide rails 64 is preferably supported by a stop 67 standing perpendicular to the support surface 02 of the second printing forme 37, which is preferably arranged rigidly in the slot 44, preferably on both longitudinal sides of the second printing forme 37 such stop 67 is arranged so that during a along the width B of the second printing form 37 directed, opposite movement of the printing plate 37 holding guide rails 64 this printing forme 37 stored by the stops 67 arranged on both sides in the plane spanned by the support surface 02 of the printing plate 37 level remains. The stops 67 strip the printing plate 37 of the spaced apart guide rails 64 by the pressure plate 37 abuts against the stops 67, wherein at the same time the printing plate 37 is removed by the movement of the guide rails 64, the vertical support. The release of the second printing plate 37 is preferably carried out by a z. B. controllable by the press belonging to the control station drive 69, the drive 69 acts on the guide rails 64 and moves them along a travel s68.

If several printing plates 37 are arranged next to each other on the forme cylinder 33 in the axial direction thereof and a plurality of printing plates 37 are arranged side by side in the shaft 44 in the axial direction of the forme cylinder 33, it is advantageous for the guide rails 64, which act on adjacent second printing plates 37, to be in the printing forme magazine 39 over the Pad 54 in two different planes, that is to be arranged vertically offset from one another, wherein in the axial direction of the forme cylinder 33 successive planes are preferably arranged alternately offset. Due to the staggered arrangement of the planes forming the first storage position of the printing plates 37, a distance a67 between side-by-side in the axial direction of the forme cylinder 33, ie adjacent printing forms 37, can be kept as low as possible. The distance a67 preferably corresponds in terms of its value to a distance which is juxtaposed on the forme cylinder 33 in its axial direction, ie, adjacent pressure forms 37. From in the axial direction of the forme cylinder 33 juxtaposed planes, ie in each case from a first storage position, placed on the pad 54 and thus each placed in their second storage position printing plates 37 can be supplied with the conveyor 57 to the forme cylinder 33 either individually or preferably simultaneously, where the latter procedure for a rapid change of printing plates 37 on the forme cylinder 33 is advantageous. In the axial direction of the forme cylinder 33 stored in different juxtaposed planes printing plates 37 can change simultaneously or at least in rapid succession in their respective second storage position. The form cylinder 33 simultaneously supplied together printing plates 37 are on the Form cylinder 33 arranged in the axial direction side by side,

In the in the Fig. 8 shown example, four second printing plates 37 are each arranged in their first storage position in the axial direction of the forme cylinder 33 side by side, each of these printing plates 37 is held at their longitudinal sides in a guide rail 64. The vertical offset of the printing plates 37 is only a few millimeters, z. B. 4 mm to 6 mm, and corresponds approximately to the overall height of the guide rails 64, preferably their simple to double height. The movement of the guide rails 64 along the width B of the second printing form 37 is z. B. by a linear displacement of the guide rails 64; However, it can also be performed by a pivoting movement of the guide rails 64, wherein the guide rails 64 are pivotable about a pivot axis, wherein the pivot axis parallel to the supported by the guide rails 64 side of the printing plate 37. Thus, a guide rail 64 z. B. attached to at least one pivot arm 68, the z. B. in the plane defined by the support surface 02 of the second printing plate 37 plane is pivotally, which in the Fig. 9 indicated by a directional arrow. The pivot arm 68, one end of which is connected to the guide rail 64 and the other end in the shaft 44 is preferably fixedly mounted, z. B. as a laterally acting on the guide rail 64 spring element 68, z. B. may be formed as a leaf spring 68, wherein the guide arm 64 connected to the pivot arm 68 by the drive 69, z. B. by a controllable, in particular remotely controllable magnet 69, in a second printing forme 37 holding or one of this printing plate 37 releasing operating position is moved. The travel s68, the movable guide rail 64 performs along the width B of the second printing plate 37, is in the range of a few millimeters, z. B. between 2 mm and 10 mm, preferably 4 mm. Preferably, a stop 67 is also provided in this embodiment, to which the printing plate 37 abuts with its supported by the guide rail 64 side, while the guide rail 64 withdraws the support by their movement of the printing plate 37. Two in the axial direction of the Form cylinder 33 adjacent printing plates 37 can strike on opposite sides of the same stop 67. During the change from the upper storage position to the lower storage position, the printing forme 37 can also slide vertically downward along one of its sides with the stop 67 so that the printing forme 37 released from the upper storage position reaches the lower storage position in a guided movement. The stopper 67 then has the function of a preferably up to the support 54 reaching side guide for a memory position changing their printing form 37.

In general terms, a method of storing at least two of the same cylinder 06; 31; 33 of a printing press successively discharged elevators 01; 36; 37 the following steps: a) a previously from the cylinder 06; 31; 33 discharged elevator 01; 36; 37 is transported from a first to a second storage position, b) the previously discharged elevator 01; 36; 37 subsequently discharged elevator 01; 36; 37 is at the first storage position of the previously discharged elevator 01; 36; 37 stored, c) the previously discharged elevator 01; 36; 37 in its second storage position and the subsequently discharged elevator 01; 36; 37 in the first storage position of the previously discharged elevator 01; 36; 37 are stored in a distance orthogonal along their length L, d) the elevators 01; 36; 37 are stored in their respective support surface 02 at least largely overlapping, preferably at least 80% overlapping or stored in their complete or almost complete coverage. The previously discharged elevator 01; 36; 37 and the subsequently discharged elevator 01; 36; 37 can be stored along their length L vertically or horizontally spaced from each other. Preferably, the previously discharged elevator 01; 36; 37 transported by a linear movement, in particular by a both memory positions directly and directly interconnecting linear movement orthogonal to its support surface 02 or by a movement of its trailing end 04, in its second storage position, which will be explained in more detail below.

It is advantageous to at least one data acquisition device 71, z. B. a code reader 71, which reads a preferably preferably on the suspension leg 14 at the trailing end 04 of each printing plate 37 mounted, area-formed coding, ie detects a feature for identifying a printing form to in a preferably electronically performed in a control unit balance with a for the form cylinder 33 provided, deposited in the control unit occupancy check to see if the introduced into the slot 44 printing forms 37 correspond to the allocation plan of the intended printing process and / or if the intended occupancy of the introduced into the slot 44 printing plates 37 are also in the correct order , Thus, even before the assembly of the printing plates 37 on the forme cylinder 33, a corresponding message, eg. B. an error message, ie a warning the operator before a faulty installation message generated and z. B. deposited on a printing unit associated control station and displayed there or on the printing unit. Further details of a system for checking the population of a printing plate magazine 39 will be described in connection with the Fig. 43 received.

The coding may preferably be in addition to a human-readable code z. B. be designed as a barcode. A barcode is a machine-readable font of different widths and gaps. The coding may be performed by a printing process, e.g. Example, an offset printing method, a flexographic printing method, a gravure printing method, a laser printing method, a thermal printing method or an ink jet printing method, on a non-printing area of the printing plate 37, preferably on the edges, applied. However, it is particularly advantageous to apply the coding in conjunction with the exposure of the printing form 37 to the same, because then no additional working step is required. In this case, the formation and arrangement of the coding z. B. on a suspension leg 13; 14 of the printing plate 37, before this suspension leg 13; 14 is bent in a bending operation.

There are different types of barcodes. Even though barcodes always form a two-dimensional array of characters, one distinguishes between one-dimensional (1-D codes), two-dimensional (2-D codes) and three-dimensional (3-D codes) barcodes, the latter forming color in the third dimension , Barcodes are usually standardized in their graphical representation as well as in their information content, z. In ISO / IEC 15415 (2-D codes), ISO / IEC 15416 (1-D codes), ISO / IEC 15418 (data structures) or ISO / IEC 15420. Known 1-D codes are e.g. Eg the alphanumeric code39 according to ISO / IEC 16388, the code128 according to ISO / IEC 15417 or the purely numerical code Interleaved 2/5 according to ISO / IEC 16390. A 2-D code, which also encodes information perpendicular to its main orientation z. B. a matrix code, z. For example, a DataMatrix code defined in ISO / IEC 16022. Matrix codes can be used with a camera system, eg. B. a CCD camera, omnidirectional read. Reed-Solomon error correction doubles the data, which can destroy about 25% of the code without compromising decoding. Other matrix codes are z. B. QR codes and Aztec codes.

The DataMatrix code exists in different versions, eg. As in the version data matrix code ECC 200, the letters ECC stand for the English expression "E rror C hecking and C orrection Algorithm" and those letters following number indicates a certain level of development of the Data Matrix codes. The DataMatrix code consists of a rectangular area whose size is variable. This surface has quadratic structural elements each having a binary valence; they are z. B. executed in black or white. An example of a DataMatrix code is in the Fig. 37 shown, with side by side z. B. two square DataMatrix code areas 101 are arranged with each square structure elements 102. For some applications, further DataMatrix code areas 101 can be joined together to form the coding, wherein the DataMatrix code areas 101 are adjacent to one another and also to one another or to one another, eg. B. in a multi-row and column arrangement can be arranged.

For a 1-D code, 101 different thicknesses must be uniquely determined in one drawing plane. In the case of the DataMatrix code, on the other hand, it can only be ascertained which valency each quadratic structural element 102 shown in the drawing plane 101 has, whether it is z. B. is formed in black or white. Moreover, a Data Matrix code requires significantly less space than a 1-D code for the same information content. To capture a 2-D code, a camera system is always required, which captures the information in two dimensions and the captured image z. B. by means of a pattern recognition z. B. evaluated by comparing the detected coding pattern or marker pattern with a stored expectation pattern. Accordingly, the camera system converts the detected structural elements 102 of the 2-D code into an electronic, preferably digital, payload. 2-D codes must be illuminated areally because of the use of a camera system with a lighting device having at least one light source. The light reflected by the 2-D codes is then reflected on an image plane of an image sensor, e.g. B. a CCD sensor or CMOS sensor, shown, wherein the image sensor component z. B. a line scan camera or a surface camera. Overall, the DataMatrix code places only minimal demands on color contrast and print quality. The light emitted by the light source of the illumination device and the spectral sensitivity of the image sensor are to be matched to the optical properties of the printing plate 37 carrying the 2-D code, in particular its reflection behavior and remission behavior. For detecting a 2-D code applied to a printing plate 37 by the exposure thereof, a laser diode or a light-emitting diode having an emission of white, yellow or green light has proved to be advantageous as the light source of the illumination device. The light source can be z. B. in the image sensor having a code reader 71 may be integrated. The design of the code reader 71 with a parameterizable automatic exposure system is advantageous. The image sensor and the light source of the illumination device are to be arranged with their respective effective direction at an angle of inclination of at least 5 ° relative to a perpendicular standing on the plane of the drawing 101 or code area 101, preferably with an inclination angle in a range between 10 ° and 60 °. To protect against paint mist and other pollution of the code reader 71 at a minimum distance of z. B. 10 mm from the code area 101 may be mounted, wherein the image sensor and light source z. B. are protected by a mineral glass or acrylic glass against pollution.

The DataMatrix code has the following four main components: A fixed boundary line 103 is used for pattern recognition and is used to calculate the rotational position of the DataMatrix code so that each reading angle is possible. A boundary line 104 opposite solid line 103, also referred to as non-closed boundary 104, is used to identify the number of rows and columns, i. H. the so-called matrix density. For the ECC 200, the element in the top right corner is always white. The boundary lines 103; 104 bound and include a memory area 106, wherein the memory area 106 contains the actual binary information in coded form. Depending on the size and / or number of the individual structural elements 102, this also defines the number of possible information. An empty zone, called a quiet zone, surrounds the DataMatrix code. It contains no information and is not used for orientation. The width of the quiet zone is one field or one line and is needed to distinguish it from other optical pixels.

The memory area 106 of the coding contains z. Example, an information on the basis of the printing plates 37 for the purpose of their identification are distinguishable from each other and / or based on a single specific printing plate 37 is traceable in their use. Thus, printing forms 37 belonging to different printed images and / or to different color separations always have a coding which differs from each other. The coding can z. B. have generated by a counter index to z. B. consecutively used or to be used printing plates 37 to consecutively count and these printing plates 37, especially those that are identical and / or used sequentially at the same mounting position of a particular forme cylinder 33, to identify in their respective order. The coding may optionally contain information about the respective installation location of the printing forme 37 in the printing press.

An alternative to the formation of the coding in the form of a bar code is the use of transponder systems, in particular radio tags, which are referred to as RFID according to their English-language abbreviation. Radio tags transmit their information contactlessly by means of an electromagnetic field. Another alternative to the formation of the coding can in punch marks, z. B. in punched holes exist.

Fig. 38 shows a printing plate 37, at the trailing Hanger 14 two encodings across the width B of the printing plate 37 are mounted spaced from each other ( Fig. 1 ), in each case z. B. two along the width B of the printing plate 37 juxtaposed DataMatrix code areas 101 each in the side region of Einhänbringels 14. Alternatively or in addition to this arrangement of codings on trailing suspension legs 14 of a printing plate 37, especially in a printing plate 37 in the panoramic format encoding be mounted in the middle region of the suspension bell 14 of this printing plate 37 ( Fig. 40 and 41 ). Each DataMatrix code area 101 can only represent a certain amount of information. Depending on the amount of information to be presented in the coding, two or more DataMatrix code areas 101 are required and preferably applied to the trailing suspension leg 14 of the printing forme 37.

The code reader 71 may, for. B. in the shaft 44, for example, on the slider 56 for resting on the support 54 first printing form 37 or at the L-shaped angle 61 for a second printing plate 37, be attached. The code reader 71 is thus preferably in or at the shaft 44 at its end remote from the forme cylinder 33 arranged, wherein a reading direction of the code reader 71 is directed either parallel to the length L of the printing plate 37 or preferably parallel to the width B of the printing plate 37. In one embodiment, the code reader 71 is preferably arranged with a linear guide movable in or on the shaft 44 or there is a preferably inclined by 45 ° to the width B of the printing plate 37 movable mirror which provides a detection or read signal from one to the printing plate 37th attached coding to a arranged on one side of the shaft 44 code reader 71 deflects, so that only a single code reader 71 is required for reading the attached to the shafts 44 stored in the printing plates 37 coding. By using only a single code reader 71 for a plurality of stored printing plates 37, significant costs can be saved. In the case of the use of only a single code reader 71, the code reader 71 or the mirror is either parallel to the width B of the printing plate 37, ie in the axial direction of the forme cylinder 33, preferably along several shafts 44 and / or along the pressure forms stacked in one of the shafts 44 37 vertically movable so that the code reader 71 or the mirror detects the coding of stored in different storage positions printing forms 37.

As already described above, in which in the Fig. 8 shown example of printing form magazines 38; 39 four printing plates 37 each arranged in their storage position in the axial direction of the forme cylinder 33 side by side. This arrangement is also adaptable to a different number of printing forms 37 arranged side by side, according to need, e.g. B. only two or six printing plates 37 can be arranged side by side. The Fig. 39 to 41 grab that in the Fig. 8 shown example. That's how it shows Fig. 39 schematically in plan view an arrangement of z. B. four juxtaposed printing plates 37 each having a length L and a width B ( Fig. 1 ), wherein in each case two adjacently arranged printing plates 37 a common code reader 71 is assigned. Each of the code readers 71 is z. B. formed as a camera system 71 or incorporated into such, each of these camera systems 71 as an image sensor 107 each z. B. has a CCD sensor 107, wherein in a detection area 108 of each CCD sensor 107 preferably at least two printing plates 37 are arranged, so that the code reader 71 can detect all arranged in its detection area 108 codings simultaneously by the image sensor 107, the detected by the detection area 108 of the code reader 71 codings simultaneously in the same Image plane maps.

In the in the Fig. 39 the example shown, the respective CCD sensor 107 is respectively directed to the trailing suspension leg 14 of the arranged in the respective detection area 108 printing plates 37. The detection area 108 of each CCD sensor 107 can be detected by an optical device, e.g. B. by a wide-angle lens, and in particular along the width B of the printing plates 37 have a preferably blunt opening angle to capture multiple encodings, in particular the respective coding of several different printing plates 37, in the same detection area 108 and thus to capture simultaneously. The CCD sensor 107 of the respective camera systems 71 is in each case arranged at a distance a71 from the trailing suspension leg 14 of the printing forms 37 arranged in the respective detection area 108, wherein this distance a71 z. B. is at least 10 mm. The detection area 108 of the image sensor 107 is shown in FIG Fig. 40 and 41 each surrounded by a dot-dash line, z. B. rectangular field, this field is in each case in the same plane as the attached to the trailing suspension leg 14 of the printing plates 37 DataMatrix code areas 101 and is also aligned parallel to the respective DataMatrix code areas 101.

The Fig. 40 and 41 each show arrangements of printing plates 37, wherein at the trailing suspension leg 14 of these printing plates 37 each at least one encoding is attached. The coding is z. B. in the form of two along the width B of the respective printing form 37 lined up DataMatrix code areas 101, each z. B. are arranged in the respective side region of the respective printing form 37 ( Fig. 38 ). In detail, the shows Fig. 40 in association with a Printing forms 37 to be occupied cylinder 33 (not shown) in the axial direction by way of example four juxtaposed shafts 44 of a printing forme magazine 39 ( Fig. 5 ), wherein in the respective wells 44 each z. B. two printing plates 37 are stored, in each case a printing plate 37 in two superposed memory positions. Preferably, at the cylinder 33 opposite end face of the shafts 44 z. B. each configured as a camera system 71 code reader 71, wherein the respective detection area 108 of each belonging to one of the camera systems 71 image sensor 107 detects the respective coding of four adjacent pressure plates 37 jointly and at the same time, in each case of two in Axial direction of the cylinder 33 adjacent to each other in two different shafts 44 arranged printing plates 37 and two in the same shaft 44 superimposed printing plates 37. The respective detection area 108 of each one of the camera systems 71 associated image sensor 107 may, for. B. an angular, in particular rectangular, preferably square cross-sectional area or z. B. also have a round, preferably elliptical or circular cross-sectional area, all recorded in the detection area 108 of the code reader 71 codes are imaged on the image plane of its image sensor 107. The cross-sectional area of the detection area 108 of the code reader 71 and the image plane of the image sensor 107 are preferably arranged parallel to each other. As a variant, it may be provided that the image plane of the image sensor 107 is subdivided into a plurality of viewing zones 109 which are preferably selectively activatable by the respective camera system 71, each coding of each of the printing plates 37 detected by the detection area 108 being exactly one of the viewing zones belonging to this detection area 108 109, ie, each of these viewing zones 109 detects exactly one of the codings detected by the detection area 108 and thus also forms exactly one of the codings detected by the detection area 108 on the image plane of the image sensor 107. In the arrangement of Fig. 40 each of the printing plates 37 is preferably assigned to exactly one of the pressure points on the cylinder 33, so that the cylinder 33 in this Example, with a total of eight printing plates 37, namely four assignable in its axial direction and two each in its circumferential direction. This arrangement can readily be supplemented with two further side-by-side shafts 44 for a 6/2 cylinder 33.

In contrast to Fig. 40 show the Fig. 41 two juxtaposed shafts 44, which are suitable for receiving at least one printing plate 37 in the panoramic format, ie, a double-width in the axial direction of the cylinder 33 printing plate 37 (FIG. Fig. 6 ). In the illustrated example, a printing plate 37 in panorama format is stored in each case in the right-hand slot 44 at two memory positions arranged one above the other; in the left slot 44 of this arrangement are stored in the lower storage position, a single printing plate 37 in the panoramic format and in the upper storage position, two printing forms 37 simple width. The stored in this arrangement printing plates 37 in the panoramic format have at least in one of its half width B near range at least one encoding, wherein the coding in each case z. B. in the form of two along the width B of the respective printing plate 37 juxtaposed DataMatrix code areas 101 is formed. If the coding applied to panorama printing plates 37 is mounted near the middle of the width B of these printing plates 37, this coding can be detected with the same arrangement of camera systems 71 as previously described in connection with US Pat Fig. 40 describe. An adjustment of these camera systems 71 is then not required. Thus, these camera systems 71 can be installed in conjunction with the shafts 44 of the printing forme magazine 39 advantageously fixed. As in the Fig. 40 and 41 represented by the placement of the coding on the trailing suspension leg 14 of the respective printing form 37 simple or double width B ensures that the coding in the detection area 108 of the camera systems 71 is arranged, wherein the detection areas 108 each z. B. in several, z. B. are divided into four viewing zones 109, each of the viewing zones 109 z. B. covers a quadrant of the respective detection area 108 and wherein with each the observation zones 109 exactly one coding on one of the printing plates 37 can be detected. The recorded in the respective viewing zones 109 images of the codes are thus z. B. sequentially readable.

Fig. 42 1 shows a device for moving a code reader 71 from a horizontal rest position to a vertical working position, wherein the terms "horizontal" and "vertical" are respectively related to the position of the cross-sectional area of the detection area 108 of the code reader 71. In the rest position, the cross-sectional area of the detection area 108 of the code reader 71 is preferably substantially perpendicular to the plane 101 of the code attached to a printing plate 37, whereas in the working position, the cross-sectional area of the detection area 108 of the code reader 71 is preferably substantially parallel to the plane 101 of the Printing form 37 attached and arranged to be detected coding. Preferably, the image plane of the image sensor 107 of the code reader 71 is thus arranged either horizontally or vertically. Only in its essentially vertical arrangement is the image sensor 107 able to image the respectively to be detected coding on its image plane.

The in the Fig. 42 The apparatus shown has two defined end positions for the code reader 71, between which the movement of the code reader 71 takes place. One or two opposite sides of the code reader 71, wherein these sides each extend longitudinally to the length L of at least one printing form 37 stored in a printing forme magazine 39, are e.g. B. on a fold-out, z. B. by at least one joint 112 subdivided linkage 111, wherein in the Fig. 42 Envelopes 113 indicate which movement of the code reader 71 and its linkage 111 take when the code reader 71 is moved from its horizontal rest position to its vertical working position or in the reverse direction. The code reader 71 is preferably arranged such that in its rest position, the image plane of its image sensor 107 is directed with its optically active side down, ie in the effective direction of gravity, so that neither dust nor dirt can be deposited on the image sensor 107. In the Working position of the code reader 71 whose image sensor 107 is directed to a trailing suspension leg 14 at least one printing plate 37. The movement of the code reader 71 from its horizontal rest position to its vertical working position - and preferably vice versa - is performed by a manual adjustment or by a preferably remotely actuable drive (not shown), wherein the drive z. B. can be operated electrically or pneumatically. The movability or pivotability of the code reader 71 is advantageous in that the accessibility of the shafts 44 of the printing forme magazine 39 is thereby improved on its end remote from the cylinder 33. The in the Fig. 42 shown device for moving the code reader 71 from its horizontal rest position to its vertical working position is in a very compact form of construction z. B. above the shafts 44 having printing plate magazine 39 is attached. For operation of the code reader 71 required connection and supply lines are not shown for reasons of clarity.

Fig. 43 shows in a simplified block diagram, a system for checking the assembly of a printing forme magazine 39, wherein this test is carried out before a change of printing plates 37 on a cylinder 33 of a printing press. In the illustrated example, four printing plates 37 are stored in shafts 44 of the printing forme magazine 39 in the axial direction of a cylinder 33 of a printing unit of the printing press. In the printing forme magazine 39 can in the shafts 44 vertically above each other z. B. two printing plates 37 may be stored so that the cylinder 33 is assignable to its lateral surface with a total of eight printing plates 37. The printing forme magazine 39 stored in the printing forme magazine 39 all have at least one coding on their trailing suspension leg 14, this coding being in each case z. B. in the form of two along the width B of the respective printing plate 37 lined-up DataMatrix code areas 101 is formed ( Fig. 38 ). At the end of the printing forme magazine 39 which is farther from the cylinder 33, two code readers 71 are installed in such a way that they are in their respective working position with the detection area 108 their respective image sensor 107 each capture the coding of at least two adjacent in the printing forme magazine 39 arranged printing plates 37. The respective coding of vertically superimposed printing plates 37 can also fall into the same detection area 108 of one of the image sensors 107 ( Fig. 40 or 41 ). Of the codes arranged in each of the detection areas 108 preferably individually and successively recorded images are converted by the respective code reader 71 into electronic, preferably digital image data, these image data are in turn fed to an evaluation unit 114, wherein the code reader 71 with the evaluation unit 114 z. B. are connected by a line or by a wireless link, this connection with their data flow in the Fig. 43 each indicated by an arrow. The evaluation unit 114 can also be used as part of a more complex, e.g. B. be formed at least one of the code reader 71 comprehensive camera system. The evaluation unit 114 can be assigned to a single camera system or to a plurality of camera systems arranged in the printing press. The evaluation unit 114 may, for. B. be integrated in a printing tower control of the printing press.

In the evaluation unit 114, the image data acquired by the individual printing forms 37 and corresponding to their respective coding are evaluated by linking with data provided to the evaluation unit 114 by a production planning system 116 as to whether the printing form magazine 39 is equipped with the right for a planned production printing plates 37, wherein this check is carried out to the effect whether in the respective slot 44 of the printing forme magazine 39, the required for the planned production printing form 37 is stored. The production planning system 116 is in the Fig. 43 abstract as a PC system, comprising a control unit, a display device and an input unit, for. As a keyboard, shown. However, the production planning system 116 may also be formed in or at least with a control station belonging to the printing press and thus into the machine control be involved, the control center data technically z. B. in a computerized system of this printing machine operating printer is involved. Because of the bidirectional data exchange between the evaluation unit 114 of the camera system and the production planning system 116, the line connection between them is indicated by a double arrow.

In particular, the evaluation unit 114 is connected to a reporting device 117, at which the evaluation unit 114 displays at least one detected discrepancy between the recognized actually stored printing form 37 and a printing plate 37 required for the planned production at this point and / or a corresponding one from the operator of the printing press emits a perceptible message. The annunciator 117 may include a visual and / or audible indicator; she can z. B. also assigned in the form of the individual shafts 44 of the printing forme magazine 39, z. B. realized by light emitting diodes, be formed like traffic lights, with a z. B. green display indicates that a preferably performed in the evaluation unit 114 matching the detected coding of a stored printing form 37 with the data of the production planning system 116 has led to any discrepancy, whereas a z. B. red indicator indicates such a discrepancy. In an interchanging of the stored in the wells 44 of the printing forme magazine 39 printing plates 37, which is one of the most common in practice in the assembly of a printing forme magazine 39 with printing plates 37 error, the interchangeability of horizontally juxtaposed memory positions can affect as well as vertically stacked Memory positions, can be displayed with the display of the annunciator 117 and the correct for the respective currently tested printing plate 37 storage position in the printing plate magazine 39. If there is not merely an exchange of printing plates 37 with regard to their storage positions in the printing forme magazine 39, but a storage position has erroneously been equipped with a printing forme 37 which is not required for the planned production, the display of the Message device 117 also point to this error. The display of the reporting device 117 may further indicate, if the coding of a printing plate 37 is unreadable, that a reading error has occurred and / or at which of the storage positions of the printing plate magazine 39 the reading error has occurred. Thus, the annunciator 117 may be capable of reporting various types of errors. If a specific error message is to be deliberately tolerated, acknowledgment by the operator of the printing press confirming this displayed error may be provided for this purpose. All the above-mentioned messages of the reporting device 117 help to increase the process reliability during operation of the printing press, because they show the operating staff of the printing machine errors in particular when equipping a printing forme magazine 39 with printing plates 37 and / or at the feeding at least one of the Druckformmagazin 39 stored printing plates 37 to a cylinder 33 and thus help the operator to avoid such errors or at least correct in time before the start of production.

The process control for the system for checking the assembly of a printing forme magazine, the details of which in conjunction with the FIGS. 37 to 43 are described in the Fig. 44 shown. The individual process steps and their respective dependency on the fulfillment of certain requirements can be taken directly from the flowchart.

Either the code reader 71 or at least one other sensor 91 may be used to monitor and / or to check whether an intended printing plate change has been carried out successfully. Errors such as a double occupancy or a faulty occupancy, ie the assembly of a printing plate 37 at an inaccurate location, are then avoidable, but at least detectable by a preferably deposited on the control station of the printing machine message before a greater damage occurs. It is also advantageous in the evaluation unit 114 of the code reader 71 belonging Camera system or in a z. B. registering device integrated in the control station, which feed or Abführbewegungen on which shafts 42; 44 of the printing form magazine 38; 39 have already been executed, because even by this registration of the feed or Abführbewegungen of printing plates 36; 37 can be concluded that the pressure point on the cylinder 31; 33, a printing forme 36; 37 to be supplied, for the installation of a new printing plate 36; 37 is ever free. Thus, it is advantageously provided that the evaluation unit 114, which is in communication with the code reader 71, and / or another registration device registers at least the supply of each printing form 37 stored in the printing forme magazine 39 to the cylinder 33, so that the evaluation unit 114 or the other registration device is from the registration at least a certain number of a certain pressure point of the cylinder 33 already supplied printing forms 37 can derive information about whether that pressure point on the cylinder 33, which is to be supplied to the currently stored in the printing plate magazine 39 37 is free for the assembly of this printing plate 37 , The process of registration includes both the preferably sensory, z. B. executed with the code reader 71 detection of a particular event, such an event z. Example, the supply of a particular stored in the printing forme magazine 39 printing plate 37 to the cylinder 33, as well as an automatic, preferably electronic recording respectively storing a corresponding event with the detected event, this information for further evaluation from the memory having them retrievable is.

If the evaluation unit 114 or the other registration device is provided with information of a production planning system 116, the evaluation unit 114 and / or the other registration device can use their respective reporting device 117 to compare the information captured by the stored printing form 37 with the information of the production planning system 116 Indicate the exchange of stored on storage positions of the printing plate magazine 39 printing forms 37. The evaluation unit 114 or the other registration device can with their respective Notifying device 117 also display the correct memory position for a printing forme 37 stored in the printing form magazine 39 at a reversed storage position and / or for a printing form 37 erroneously stored in a storage position of the printing forme magazine 39 and / or for a printing forme 37 stored at a storage position of the printing forme magazine 39 indicate unreadable coding.

B. inclined support 72, which as well as the support 54 in the shaft 44 to provide on the forme cylinder 33 to be mounted printing plates 37 is preferably not formed over the entire surface, but in the form of parallel strips 72 or slides 72, wherein the inclination of the support 72 the Shaft 42 preferably expands on the side facing away from the forme cylinder 33, whereby this shaft 42 is more accessible to the operator on the side facing away from the forme cylinder 33, which facilitates the removal of stored in the slot 42 printing plates 37. The support 72 in the shaft 42 is z. B. inclined to a horizontal H by an inclination angle δ, wherein the inclination angle δ z. B. between 5 ° and 15 °, preferably about 7 ° can be. In the in the Fig6 As shown, the shaft 42 for receiving the forme cylinder 33 remote printing plates 37 is below a shaft 44 for providing on the forme cylinder 33 to be mounted printing plates 37, which is a preferred, but not mandatory arrangement. The shafts 42; 44 may also be layered in reverse order or may be separate.

A preferred embodiment of the shaft 42 provides that in the shaft 42 in the axial direction of the forme cylinder 33 next to each other at least two printing plates 37 can be stored. This embodiment enables a particularly rapid removal of printing plates 37, in particular if at least two printing plates 37 can be arranged on the forme cylinder 33 in its axial direction, because a plurality of printing plates 37 can be removed simultaneously from the forme cylinder 33. If on the forme cylinder 33 in its axial direction z. B. at least four printing plates 37 can be arranged, it is advantageous for stability reasons, for. B. two shafts 42 in the axial direction of the forme cylinder 33 next to each other. Each defined by the width B of a printing plate 37 storage space in one of these shafts 42 is then formed such that there are at least as many printing plates 37 can be stored as printing plates 37 can be arranged on the forme cylinder 33 along its circumference, wherein the storage of the printing plates 37 at each storage space on top of each other in a stack. It can be provided that in each of the shafts 42 up to ten, but at least up to eight printing plates 37 can be stored so that discharged from the forme cylinder 33 printing plates 37 can be collected in the shafts 42 and the shafts 42 is not necessarily after each change of the printing plates 37 must be cleared by the operator. Regardless of the number of juxtaposed wells 42, the storage locations in the axial direction of the forme cylinder 33 have the same close spacing from each other as the printing formes 37 are arranged on the forme cylinder 33.

B. a roller 73 is formed and has the task of leading the trailing end 04 of a forme cylinder 33 to be removed from the printing plate 37 into the slot 42. A distance a73 of the guide element 73 from the lateral surface 07 of the forme cylinder 33 is preferably not much greater than the length 114 of the folded Einhänbringels 14 at the trailing end 04 of the printing plate 37, in particular, the distance a73 of the guide member 73 has a value between the simple and the double Length I14 of the suspension bell 14 on ( Fig. 6 ). Since one of the forme cylinder 33 to be removed printing plate 37 with its printed image side the Guiding element 73 touches, is their contact with a rotatably mounted rolling element 73 for their surface gentler than a slide over a planar rigid wedge 73. This aspect is particularly important if the printing plate 37 is to be used again and thus damage to their printed page by scratches or grinding marks is to be avoided. On the guide member 73, a sensor 91 may be mounted, either in contact with the forme cylinder 33 to be removed from the printing plate 37 or advantageously contactless, z. B. inductive, checks whether the suspension leg 14 has actually solved at the trailing end 04 of the forme cylinder 33 to be removed from the printing forme 37 after actuation of the arranged in the channel 08 of the forme cylinder 33 holding means 21. With its test, the sensor 91 sends a signal z. B. to the press belonging to the control room. On the basis of the signal emitted by the sensor 91, a decision is made as to whether the process of discharging a printing forme 37 to be removed from the forme cylinder 33 can be continued or whether measures for eliminating a malfunction must be initiated. On the guide member 73, preferably a plurality of sensors 91 are provided in the axial direction of the forme cylinder 33, for. B. four or six, namely in each case at least one sensor 91 for each on the forme cylinder 33 in the axial direction next to each other can be arranged printing form 37th

In a preferred exemplary embodiment, the suspension leg 14 at the trailing end 04 of the printing forme 37 to be removed from the forme cylinder 33 preferably passes on a first ramp 74 spaced from the guide element 73 before reaching the support 72 in the shaft 42, wherein the first ramp 74 initially rises in the direction of the support 72 and, after a summit point 76, drops towards the support 72. The first ramp 74 is preferably rigidly connected to the support 72. In the course of the introduction of the forme cylinder 33 to be removed from the printing plate 37 into the slot 42 hits her suspension leg 14 at the trailing end 04 on a second ramp 77, the flank of her summit point 78, ie that of the forme cylinder 33rd turned away side, preferably abruptly steeply towards the support 72 towards falls. In the direction in which the printing forme 37 is introduced into the slot 42, a77 (a) is at a short distance. Fig. 14 ) arranged behind the summit point 78 with the second ramp 77 rigidly connected stop 79 to which the suspension leg 14 abuts the trailing end 04 of the printing plate 37. The distance a77 has in this case a value of a few millimeters, preferably a value of less than the simple length I14, in particular less than half the length I14 of the folded Einhänbringels 14 at the trailing end 04 of the printing plate 37th If the suspension leg 14 at the trailing end 04 of the printing forme 37 strikes against the stop 79, it preferably engages behind the second ramp 77, in that the suspension leg 14 engages in the space formed by the distance a77. The second ramp 77 and the stop 79 connected to it are linearly movable by a conveyor 81 and parallel to the support 72 in order to completely convey the printing forme 37 to be removed from the forme cylinder 33 into the shaft 42. The conveyor 81, which forms in particular together with the steep flank on the second ramp 77 for the folded suspension leg 14 at the trailing end 04 of the printing plate 37a the printing plate 37 in the slot 42 promoting entrainment is z. B. as a belt drive 81 or as a linear drive 81, preferably as a pneumatic linear drive 81, in particular as a rodless, double-acting linear actuator 81 is formed. Both the first ramp 74 and the second ramp 77 consist z. B. not from full-surface planes, but from several parallel as the tines of a comb arranged guide rails. The second ramp 77 may, for. B. be formed from one or more correspondingly bent metal strip.

On the side facing away from the forme cylinder 33, a lifter 82, in particular a printing form lifter 82 is arranged in the shaft 42, wherein the printing form lifter 82, for example, a preferably perpendicular to the support 72 movable piston 83, at the end of a z. B. L-shaped, in particular U-shaped Hebarm 84 is arranged, wherein the bent suspension leg 14 is set up at the trailing end 04 of the printing plate 37 on the lifting arm 84 or set encompassing. The printing form lifter 82 preferably has two stable operating positions, namely a stable operating position with the piston 83 retracted, in which the lifting arm 84 is below the level defined by the support 72, and another stable operating position with the piston 83 extended, in which the lifting arm 84 the printing forme 37 removed from the forme cylinder 33 lifts from the support 72. The printing form lifter 82 executes a stroke s82 which is greater than the length l14 of the bent-in suspension element 14 at the trailing end 04 of the printing forme 37. Preferably, the stroke s82 has a value between the single length and the double length l14 of the suspension element 14. The printing form lifter 82 thus lifts a printing forme 37 removed from the forme cylinder 33 from a provisional first storage position to a final, second storage position.

Above the printing form lifter 82, in particular above its lifting arm 84, a preferably pivotable about a substantially parallel to the width B of the printing plate 37 extending pivot axis securing element 86 is arranged, for. B. in the form of a strip-like flap 86, whose or the lower edge is located at a distance a86 from the lifting arm 84, wherein the distance a86 is preferably dimensioned smaller than the length of the bent I14 14 hanging 14 at the trailing end 04 of the printing plate 37th In the Fig. 6 indicates a direction arrow to the pivoting of the fuse element 86. The securing element 86 secures a printing form 37 lifted by the printing form lifter 82 against unintentional slippage in the shaft 42 or removal from the shaft 42. Thus, an operator first has to pivot the securing element 86 before the raised printing form 37 can be removed from the shaft 42.

Another embodiment of arranged in the shaft 42 assemblies is in the 10 to 12 shown. This embodiment provides a preferably in middle region of the support 72 rigidly arranged stop 79 before, with a linearly along the support 72 movable conveyor 81 connected printing form lifter 82 lifts the folded suspension leg 14 at the trailing end 04 of the forme cylinder 33 to be removed printing plate 37 via the stop 79 and the printing plate 37 pulls on its folded suspension leg 14, preferably in its raised by the pressure molding jack 82 state to the side facing away from the forme cylinder 33 end of the shaft 42. The conveyor 81 and the printing form lifter 82 may be positively coupled such that the printing form lifter 82 then lifts the bent suspension leg 14 of the printing plate 37 as soon as the conveying device 81 carries out a movement in the direction away from the forme cylinder 33. Furthermore, a further printing form lifter 87 is provided between the stop 79 and the forme cylinder 33 facing the end of the shaft 42, which raises the leading end 03 of a form cylinder 33 remote, inserted into the slot 42 printing form 37 so far that another from the forme cylinder 33rd to be removed printing form 37 between the support 72 and the raised printing plate 37 into the slot 42 is inserted.

Based on FIGS. 13 to 35 In particular, methods for changing printing plates 37 on a forme cylinder 33 will now be explained. It is assumed that two printing plates 37 are arranged in the upper shaft 44 for providing new printing forms 37 to be mounted on the forme cylinder 33, that two printing plates 37 are placed on the forme cylinder 33 along its circumference and that the lower shaft 42 is for receiving the Form cylinder 33 distant printing plates 37 empty, ie free of printing plates 37 is.

The forme cylinder 33 rotates the opening 09 of a channel 08, in which the suspension leg 14 is held at the trailing end 04 of the forme cylinder 33 to be removed from the printing plate 37 by a holding means 21, in a first position, which is below the guide 42 belonging to the lower guide member 73 located. The controllable, preferably pneumatically actuable pressure element 24 is set to the forme cylinder 33 ( Fig. 13 ).

The preferably pneumatically actuable actuating means 23 pivots the holding means 21 against the force of a spring element 22, whereby the suspension leg 14 at the trailing end 04 of the printing plate 37 due to its elastic residual stress from the opening 09 snaps and abuts the guide member 73. The employed pressing element 24 secures the printing forme 37 against a further release from the lateral surface 07 of the forme cylinder 33 (FIG. Fig. 14 ).

The forme cylinder 33 rotates counter to its production direction P and pushes the trailing end 04 of the printing forme 37 into the shaft 42. When the printing forme 37 is inserted into the shaft 42, the suspension leg 14 slides along the trailing end 04 of this printing forme 37 along the guide element 73 then adjusts to the first ramp 74 belonging to the shaft 42. The suspension leg 14 slides up the ramp 74 to above its summit point 76 and then reaches the support 72. While the pressing member 24 is still employed on the forme cylinder 33, the printing plate 37 is further rotated into the shaft 42 by the rotation of the forme cylinder 33 against its production direction P. inserted. In this case, their suspension legs 14 at the trailing end 04 also overcomes the second ramp 77 connected to the conveying device 81 and abuts against the stop 79 connected to the second ramp 77 (FIG. Fig. 15 ).

The pressing element 24 is turned off by the forme cylinder 33. By the impact of Einhänlegeels 14 of the trailing end 04 on the stop 79, the preferably form-fitting at the front edge 16 of the opening 09 hinged folded suspension legs 13 at the leading end 03 of the printing forme 37 from the opening 09. The pressure plate 37 is now with its leading End 03 free on the lateral surface 07 of the forme cylinder 33 on. The forme cylinder 33 has the release of the Einhängebelt 14 at the trailing end 04 to now performed less than half a turn. The folded suspension leg 14 at the trailing end 04 has hooked between the second ramp 77 and the stop 79. The conveying device 81 connected to the second ramp 77 and the stop 79 can now completely feed the printing plate 37 into the shaft 42 (FIG. Fig. 16 ).

The pressure plate 37 is removed from the forme cylinder 33 and is in its length L in the shaft 42. Its suspension leg 14 at the trailing end 04 is located on the summit point 78 of the second ramp 77, while their leading end 03 on the summit point 76 of the first ramp 74th rests, whereby at least the suspension leg 13 preferably hangs freely at the leading end 03. The storage of the printing plate 37 in the shaft 42 is thus preferably carried out by a support at two points, namely on the summit points 76; 78 of the two ramps 74; 77 ( Fig. 17 ).

The z. B. pneumatically actuated Druckformheber 82 lifts the retracted into the slot 42 printing plate 37 at its trailing end 04 to just below the fuse element 86, wherein the suspension leg 14 stands up on the associated with the printing forme lifter 82 lifting arm 84 ( Fig. 18 ).

While a first to be mounted on the forme cylinder 33 printing forme 37 with its folded Einhänbringeln 13; 14 rests on the support 54 in the upper shaft 44, the forme cylinder 33 continues to rotate counter to its production direction P in a second position until the opening 09, from which the suspension leg 13 at the leading end 03 of the previously removed from the forme cylinder 33 printing plate 37 has been solved has passed a contact point 88 of the pressure element 24 applied to the forme cylinder 33 and the rear edge 17 of the opening 09 in the production direction P of the forme cylinder 33 is at a distance a88 from the contact point 88, the distance a88 being in the range of a few millimeters, preferably less than 30 mm, and thus an arc length of less than a thirtieth of the circumference of the forme cylinder 33 corresponds. The first position of the forme cylinder 33 for removing a printing plate 37 arranged thereon is generally not identical with its second position for receiving a new printing forme 37. The pressing element 24 is preferably applied to the forme cylinder 33, while the opening 09 passes the contact point 88 or after passing the contact point 88. The alignment device 51, which is arranged close to the forme cylinder 33, pivots with its previously preferably horizontally oriented diametrical stops 52; 53 preferably by 90 ° in a vertical position, so that a matched to the width B of the forme cylinder 33 to be mounted on the printing plate 37 stop 52; 53 immersed in a defined by the support 54 in the shaft 44 transport plane for the mounted on the forme cylinder 33 printing plate 37 and immersed on the forme cylinder 33 to be mounted printing plate 37 during its transport from the slot 44 to the stop 52; 53 page register moderately aligned to the forme cylinder 33 ( Fig. 19 ).

The first printing forme 37 to be mounted on the forme cylinder 33 rests with its suspension leg 14 at its trailing end 04 on the stop 56 connected to a conveying device 57. The conveyor 57 is set in operation, so that the stop 56 in a direction preferably directed tangentially to the forme cylinder 33, the first printing form 37 as far from the shaft 44 moves until its leading end 03 touches the Angestelltenelement 24 attached to the forme cylinder 33 and the this leading end 03 be bent suspension legs 13 between the rear in the direction of production P of the forme cylinder 33 edge 17 of the opening 09 and the contact point 88 of the pressure element 24 on the forme cylinder 33 ( Fig. 20 ).

The forme cylinder 33 changes its direction of rotation and begins to rotate in its production direction P, whereby the suspension leg 13 erected on the forme cylinder 33 slips into the opening 09 at the leading end 03 of the printing forme 37 and preferably forms a positive fit at the front edge 16 of the opening 09 mounted ( Fig. 21 ).

As a result of the further rotation of the forme cylinder 33 in its production direction P, the printing forme 37, which is suspended with its suspension leg 13 in the opening 09, is completely conveyed out of the shaft 44 and mounted on the forme cylinder 33. During winding, the printing forme 37 is rolled onto the forme cylinder 33 by the pressing element 24 placed against the forme cylinder 33. After half a revolution of the forme cylinder 33 in its production direction P, the pressing element 24 presses the folded suspension leg 14 at the trailing end 04 of the printing forme 37 into the opening 09. The retaining means 21 in the channel 08 belonging to this opening 09 has been released and is then inserted into the one Operating position brought in which it introduced into the opening 09 suspension leg 14 at the trailing end 04 of the printing forme 37 z. B. fixed by a clamp. The conveyor 57 drives the stop 56 connected to it again into its end position on the side remote from the forme cylinder 33 in the shaft 44 (FIG. Fig. 22 ).

The pressure element 24 is turned off by the forme cylinder 33 and the alignment device 51 pivots with its diametrical stops 52; 53 again preferably in a horizontal position. With the method steps described so far, a change of a first printing plate 37 on the forme cylinder 33 is completed by a used printing plate 37 removed and a new printing plate 37 was mounted. This change of a printing plate 37 can be completed with the described device in a very short time, preferably in less than a minute. The forme cylinder 33 is then ready for production again ( Fig. 23 ).

The change of another, z. B. on the forme cylinder 33 along its circumference arranged second printing form 37 begins with the fact that preferably during the previous ongoing production of an operator, the new second printing plate 37 is inserted into the slot 44. In this case, the second printing form 37 of a controllable, preferably pneumatically controllable printing form holder 58 held over the support 54 by the printing forme 37 z. B. either at their ends 03; 04 between two stops 61; 62 is clamped, wherein at least one of the stops 61; 62 is movable, or by the printing plate 37 is inserted at its longitudinal sides in guide rails 64, wherein at least one of the guide rails 64 along the width B of the printing plate 37 is movable. When the printing form holder 58 releases the printing plate 37 by its holding the printing plate 37 elements, for. B. the stops 61; 62 or the guide rails 64, their distance, z. B. a58, each other at least briefly increase, the printing plate 37 falls on the support 54 and is there with their Einhänbringeln 13; 14 on ( Fig. 24 ).

To another, z. B. second printing form 37 from the forme cylinder 33, the forme cylinder 33 rotates according to the Fig. 13 explained method, the opening 09 of the channel 08, in which the suspension leg 14 is held at the trailing end 04 of the forme cylinder 33 to be removed second printing plate 37 by a holding means 21, in the first position, which is below the lower shaft 42 belonging to guide member 73rd located. The controllable, preferably pneumatically actuable pressure element 24 is set to the forme cylinder 33 ( Fig. 25 ).

According to the to Fig. 14 explained method pivots the preferably pneumatically actuable adjusting means 23, the holding means 21 against the force of the spring element 22, whereby the suspension leg 14 at the trailing end 04 of the second printing form 37 due to its elastic residual stress from the opening 09 snaps and abuts the guide member 73. The employed pressing element 24 secures the second printing forme 37 against further release from the lateral surface 07 of the forme cylinder 33 (FIG. Fig. 26 ).

The forme cylinder 33 rotates counter to its production direction P and thereby pushes the trailing end 04 of the second printing forme 37 into the shaft 42. At the introduction the printing form 37 in the shaft 42 of the suspension leg 14 slides at the trailing end 04 of this printing plate 37 along the guide member 73 along and then turns on the shaft 42 belonging to the first ramp 74. The suspension leg 14 of the second printing form 37 slides up the ramp 74, wherein it slides under the resting in the shaft 42, resting on the summit point 76 of the first ramp 74 first printing plate 37 and the summit point 76 overhanging, directed to the forme cylinder 33 leading end 03rd lifts, while the suspension leg 14 of the second printing form 37 exceeds the summit point 76 of the first ramp 74 and then reaches the support 72. While the pressing member 24 is still employed on the forme cylinder 33, the second printing forme 37 is pushed further into the slot 42 by the rotation of the forme cylinder 33 counter to its production direction P. In this case, the suspension leg 13 slides at the leading end 03 of resting in the shaft 42 first printing plate 37 on the printed image side of the shaft 42 promoted second printing plate 37. In the course of the suspension leg 14 overcomes at the trailing end 04 of the second printing plate 37auchauch with the conveyor 81st connected second ramp 77 and abuts against the second ramp 77 connected to stop 79 ( Fig. 27 ).

The pressing element 24 is turned off by the forme cylinder 33. By the impact of the suspension handle 14 of the trailing end 04 on the stop 79, the preferably positively connected at the front edge 16 of the opening 09 hinged folded suspension legs 13 at the leading end 03 of the second printing form 37 from the opening 09. The suspension leg 13 with its leading end 03 is now free on the lateral surface 07 of the forme cylinder 33. The forme cylinder 33 has performed from loosening the Einhänlegeels 14 at the trailing end 04 until now again less than half a turn. The bent suspension leg 14 at the trailing end 04 hooks between the second ramp 77 and the stop 79 a. The lifting arm 84 of the printing form lifter 82 lowers, whereby the previously held at its trailing end 04, resting in the shaft 42 first printing plate 37 on an integrally formed on the stop 79 web 89 is discontinued, wherein the web 89 has a relation to the support 72 vertical height h89 whose value is greater than the length I14 of the folded Einhänbringels 14 at the trailing end 04 of the second printing plate 37. The height h89 preferably has a value between the single and double length I14 of the bent-in suspension element 14 at the trailing end 04 of the second printing plate 37 ( Fig. 28 ).

The conveying device 81 connected to the second ramp 77 and the stop 79 now pulls the second printing plate 37 completely into the slot 42, with the first and second printing plates 37 being arranged in the slot 42 of their length L one above the other. The conveyor device 81 forms together with the second ramp 77 and the stop 79 for the folded suspension leg 14 at the trailing end 04 of the introduced into the slot 42 printing plate 37 a driver device ( Fig. 29 ).

The printing form lifter 82 now lifts with its lifting arm 84, preferably the trailing end 04 of both arranged in the shaft 42 printing plates 37 to the fuse element 86 at. The leading end 03 of the second printing plate 37 rests with a directed to the forme cylinder 33 overhang on the summit point 76 of the first ramp 74 and the folded suspension leg 13 at the leading end 03 of the first printing plate 37 is on the leading end 03 of the second printing plate 37 ( Fig. 30 ).

To mount the ready in the upper shaft 44 second printing plate 37 of the forme cylinder 33 continues to rotate counter to its production direction P back to the second position until the opening 09, released from the suspension leg 13 at the leading end 03 of the previously removed from the forme cylinder 33 second printing plate 37 has passed through the contact point 88 of the Abrückelement 24 employed on the forme cylinder 33 and the rear edge 17 of the opening 09 in the direction of production P of the forme cylinder 33 is at a distance a88 from the contact point 88 Distance a88 is in the range of a few millimeters, preferably less than 30 mm, and thus corresponds to an arc length of less than a thirtieth part of the circumference of the forme cylinder 33 ( Fig. 19 ). The pressing member 24 is preferably made to the forme cylinder 33, while the opening 09 passes the contact point 88 or after it has passed the contact point 88. The alignment device 51, which is arranged close to the forme cylinder 33, pivots with its previously preferably horizontally oriented diametrical stops 52; 53, preferably by 90 ° in a vertical position, so that a matched to the width B of the forme cylinder 33 to be mounted on the second printing plate 37 stop 52; 53 immersed in a defined by the support 54 in the shaft 44 transport plane for the second printing plate 37 to be mounted on the forme cylinder 33 and the second printing forme 37 to be mounted on the forme cylinder 37 during its transport from the shaft 44 to the stop 52; 53 page register moderately aligned to the forme cylinder 33 ( Fig. 31 ).

The second printing forme 37 to be mounted on the forme cylinder 33 rests with its suspension leg 14 at its trailing end 04 on the stop 56 connected to the conveying device 57. According to the to Fig. 20 explained method, the conveyor 57 is put into operation, so that the stop 56 in a direction preferably directed tangentially to the forme cylinder movement 33 the second printing form 37 so far from the shaft 44 until its leading end 03 touches the Anhaltelement 24 employed on the forme cylinder 33 and the suspension leg 13 bent at this leading end 03 rises between the rear edge 17 of the opening 09 and the contact point 88 of the pressure element 24 on the forme cylinder 33 in the direction of production P of the forme cylinder 33 ( Fig. 32 ).

According to the to Fig. 21 explained method changes the forme cylinder 33 its direction of rotation and begins to rotate in its production direction P, whereby the raised on the forme cylinder 33 suspension leg 13 at the leading end 03 of the second printing form 37 slips into the opening 09 and preferably in a form-fitting manner the front edge 16 of the opening 09 mounted ( Fig. 33 ).

As a result of the further rotation of the forme cylinder 33 in its production direction P, the second printing forme 37, which is suspended by its suspension leg 13 in the opening 09, is completely conveyed out of the shaft 44 and drawn onto the forme cylinder 33. During winding, the second printing plate 37 is rolled onto the forme cylinder 33 by the pressing element 24 placed against the forme cylinder 33. After half a revolution of the forme cylinder 33 in its direction of production P, the pressing member 24 presses the folded suspension leg 14 at the trailing end 04 of the second printing form 37 in the opening 09. The holding means 21 in the channel 08 associated with this opening 09 was released and is then in brought that operating position in which it introduced into the opening 09 suspension leg 14 at the trailing end 04 of the second printing forme 37 z. B. fixed by a clamp. The conveyor 57 drives the stop 56 connected to it again into its end position on the side remote from the forme cylinder 33 in the shaft 44.
